Note 8: Typical figures are at T J = 25˚C, and represent most likely parametric norms.
Note 9: Test limits are guaranteed to National’s AOQL (Average Outgoing Quality Level). Performance is guaranteed only at V
REF
= 1.4V and a clock duty cycle
of 50%. The limits for V
REF
and clock duty cycle specify the range over which reasonable performance is expected. Tests are performed and limits guaranteed with
clock low and high levels of 0.3V and V D −0.3V, respectively.
Note 10: I
DR
is the current consumed by the switching of the output drivers and is primarily determined by the load capacitance on the output pins, the supply
voltage, V
DR
, and the rate at which the outputs are switching (which is signal dependent). I
DR
= V

(C

) where V
DR
is the output driver
power supply voltage, C
n
is the total capacitance on the output pin, and f
n
is the average frequency at which that pin is toggling.
